Their first model had 3 strands.
too silly
Watson & Crick constructed the very first model of DNA :) is that what you were looking for ?
Watson and Crick proposed the double helical structural model of the DNA
James Watson and Francis Crick are credited with building the first three-dimensional model of DNA in 1953, based on data collected by Rosalind Franklin and Maurice Wilkins. Their model proposed the double helix structure of DNA that has since become widely accepted.
James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953. They built upon the work of other scientists, such as Rosalind Franklin and Maurice Wilkins, to develop their model.

Watson and Crick's model DNA in the shape of a double helix.
a DNA model
James Watson and Francis Crick, along with other researchers such as Rosalind Franklin and Maurice Wilkins, are credited with discovering the double helix structure of DNA in 1953. Watson and Crick's model was based on X-ray crystallography data from Franklin and Wilkins.
